The disequilibrium between traffic supply and demand leads to unbalanced traffic flow in urban transportation networks. By analyzing the mutual influence between the traveler route selection and signal timing, a bi-level program model is proposed in order to optimize transportation network efficiency. In light of the similarity between the game theory and the bi-level program, some simple changes are made for the purpose of simplifying the computation of the problem. Finally, a practical network is designed to validate the bi-level program model. Results indicate that the model can improve road network efficiency and decrease vehicle delays.
